with the latest private preview we can provide base environment libraries from DAB yaml as follows, i am exploring if there is any way we can directly provide base_environment_path instad:

    environment_key: default
environments:
  - environment_key: default
    spec:
      environment_version: '3'
      dependencies:
        - --index-url https://pypi.org/simple
        - pgpy
        - paramiko
        - xxxx.whl
